Question

Sulphuric acid is the king of chemicals. If you need 5 moles of sulphuric
acid for a reaction, how many grams of it will you weigh?​

Answer 1

Answer:

490 grams

Explanation:

the weight of 1 molecule of H2SO4 is

H2=2

S=32

O4=64

sum=98

then 5 molecules will weigh=5*98

=490 grams

Answer 2

Answer:

It will weigh $490$ grams.

Explanation:

For one mole of molecule of sulphuric acid, $H_{2}S0_{4}$

moles of hydrogen $=2$

moles of sulphur $1=32$

moles of oxygen $=4=64$

Sum is $2+32+64=98$

for five moles, weight is $490$ grams
