Question

what is the mass of 0.7 mol of h2so4? molar mass h2so4 = 98.09 g/mol 0.7 mol h2so4 = ? g h2so4

Explanation:

Step1: Recall mass - mole formula

$m = n\times M$ where $m$ is mass, $n$ is amount in moles and $M$ is molar mass.

Step2: Substitute given values

$n = 0.7\ mol$ and $M=98.09\ g/mol$, so $m=0.7\ mol\times98.09\ g/mol$.

Step3: Calculate the mass

$m = 68.663\ g$

Answer:

$68.663$
