Answer:
Molarity of a solution that contains 3.11 mol of NaNO3 is 1,24 M
Explanation:
We understand molarity as the number of moles of solute that are contained in 1 L of solution, then if in a solution of 2.50 L we have 3.11 moles, it remains to calculate how many moles do we have in 1 liter.
2,50 L .......... 3,11 moles
1 L .................. x
X = ( 1 L x 3,11 moles) / 2,50 L = 1,24

Answer:
= 55.7g
Explanation:
12g of carbon burnt to produce 5x10^2KJ
So, 5x10^2KJ(12g/393.5KJ)=15.2g
Then mas of CO2 is 44g
So, 15.2g(12g/44g)=57.7g
