If you could bare with the long story and give me some advice, I would appreciate it a lot! :)

Okay so basically my friend, who is a girl and I, have always liked each other.. it's really hard to explain, we've been together before and the relationship was great but we ended up breaking up, partly because I was too immature (I was young when we last dated) we've grown up a lot and we always have talked, even straight after we broke up, we've always been that type of "couple".. hard to explain but we'll always like each other.

We've both talked on numerous occasions and talked about how it would be great to get together, we're just comfortable with each other like that.

But here's the thing, a lot has changed.. I've grown up and tried new things, basically I smoke pot, not heavily, it's just one of those things where you're out with your friends and you do it and have a laugh and a good time, nothing weekly or daily.

Her last boyfriend she had smoked pot and she dumped him straight away.

I'll gladly stop for us to be together, it's not a big issue, not really addicted to it..

But I do want to tell her that I've done it a few times, partially because I want there to be nothing between us.

So like, I'm torn up whether I should tell her or not, because I don't want her to stop liking me and I really do like her too.

But she's one of those girls where "if you've smoked pot you're disgusting"

Please.. I need some advice!

(preferably from a woman's perspective)

I'm stumped at these questions, I have absolutely no idea on what or how to do them, if someone could just show me the steps on how to work out one of each I could do the rest:

Find the volume of the following gas at STP:

0.44 moles ammonia

Find the number of moles in the following volumes of gas:

20.44L nitrogen gas - RTP

76.9L chlorine gas - STP

Calculate the following volume occupied:

2.08 carbon monoxide - STP

11.7g water - RTP

Calculate the mass of the following:

3.5L oxygen gas - STP

6.01L sulfur trioxide - RTP

I don't understand what STP and RTP are?? Any help would be appreciated! Thank You in advance!

This topic is the most confused I've been in chemistry haha

For example:

Find the mass of 3 moles in:

Ca(OH)2 ?

Confused on how to do this, any help would be appreciated !

Okay so the run down is I'm terrible at Chemistry, and I'm sort of stuck in the position where I have to do it because there is absolutely no way of getting out of it, I just need a few questions answered:

1) How do you figure out how many molecules an atom has?

2) How do you figure out how much ions are in a molecule/atom? (Using the periodic table)

3) The best way of doing a balanced equation

4) The best way of doing a Complete Ionic equation

5) The best way of doing a Net Ionic equation

I'm just horrific at the subject, any help would be much appreciated! :-)

Are their any shops in the city in Sydney on George St that sell posters? Help would be much appreciated! :-)

IMO it's Kerser, you can't deny that he's taken Aus hip hop by storm
