Chemistry
1 answer:
Gre4nikov [31]3 years ago
7 0

Answer:

0.2491

Explanation:

1mole of a gas contains 6.02 × 10²³molecules

x moles will contain 3.408 × 10²¹

x = 1 × 3.408 × 10²¹/ 6.02 × 10²³

= 5.66 × 10^-3moles

Mole = mass/ molar mass

mass = Mole × molar mass

= 5.66 × 10^-3 × 44.01

= 249.0966 × 10^-3

= 0.2490966

to 4 decimal places = 0.2491
