Question

how many gm in 0.2 mole H2SO4 and How?​

Answer 1

Answer:

THEre are (2×1+32×1+16×4)g In one mole

then in 0.2 moles

no if g = 0.2×98 = 19.6 grams. ANSWRR..

Answer 2

$\huge \fcolorbox{red}{pink}{Solution :)}$

Given ,

The mole of H2SO4 is 0.2 g/mol

The molecular mass of H2SO4 is 98 u { because , (1×2 + 32 + 16×4) is 98 }

We know that ,

$\sf \large \fbox{Mole = \frac{Given \: mass}{Molecular \: mass}}$

Substitute the known values , we get

0.2 = Given mass/98

Given mass = 19.6 gram

Hence , 19.6 gram of H2SO4 contain 0.2 mole
