6.023*10^26 molecules of hydrogen gas into mass in gram

Mass = 2000 g

Explanation:

Given data:

Number of molecules of hydrogen = 6.023×10²⁶

Mass of hydrogen = ?

Solution:

1 mole of hydrogen contain 6.022×10²³ molecules

6.023×10²⁶ molecules× 1 mol/ 6.022×10²³ molecules

1.00 ×10³ mol

1000 mol

Mass of hydrogen:

Mass = number of moles × molar mass

Mass = 1000 mol × 2 g/mol

Mass = 2000 g

ok whats the question if not i cannot you i need question and need a thing to answer
