Question

Which of the following has the maximum mass ?
(a) 20g of phosphorus.
(b) 5 moles of water.
(c) 12 x 1024 atoms of hydrogen.
​

Answer 1

Hi there,

☆ The answer is (b)

● The mass of 5 mole water is equal no of moles × molar mass of water

■ 5× 18 = 90 grams

● The mass of 12×10^24 of atoms of hydrogen is equals no of atoms ÷ avogadro's no × atomic mass of hydrogen

■ = 12×10^24 ÷ 6×10^23 × 1

20 grams

☆ So the b is the maximum mass

♡ Hope the answer is helpful

Plz mark it as brainliest if u satisfied
