1M=1 mole per litre
in the equation i'm relating this to , will the 2Hcl is this equation make a difference to the amount of moles of acid
2HCl+Na2CO3=2NaCl=H2=CO2

Number of mol = (vol x Molarity)/1000
v = 20
M = 2.0
Now you can work it out.

The formula for Molarity is Moles = Volume (Liters) x Molarity (Moles per Liter).
That being said, the moles of Hydrochloric acid can be found by multiplying the 20mL (0.020L) by 2.0M to get 0.04 Moles (this is with correct sigfigs, as the value with the least is our given volume, 20mL, which only has one sigfig, so our final answer must also be to that number of sigfigs).
