Question

calculate the number of moles in 44.8g of sulphur dioxide


​

Answer 1

Answer:

2 mol

Explanation:

at ntp 1 mol of any gas = 22.4 L

1L= 1/22.4 mol

44.8= 1/22.4*44.8 mol

= 2 mol

Answer 2

no. of moles = given mass ÷ molar mass

here mass of sulphur dioxide is 44.8 g

molar mass of sulphur dioxide is 64.066 g / mol

while using the formula we get ,

no.of moles = given mass ÷ molar mass

= 44.8 ÷ 64.066

=0.69
