Which of the following has the highest mass?

Question

Which of the following has the highest mass? (A) 20 g of sulphur (B) 4 mol of carbon dioxide (C) 12 × 1024 atoms of hydrogen (D) 11.2 L of helium at N.T.P.

Tardigrade Admin · Accepted Answer

(b) Molecular mass of CO 2=44 g mol -1 ∴ 4 mol of CO 2=44 × 4=176 g (c) 6.023 × 1023 atoms of hydrogen has mass =1.008 g =12 × 1024 atoms of hydrogen has mass =20.1 g (d) 22.4 L of helium at N.T.P. has mass =4 g 11.2 L of helium at N.T.P. has mass =2 g Thus; 4 moles of CO 2 has maximum mass

Q. Which of the following has the highest mass?

20 g of sulphur

4 mol of carbon dioxide

$12 \times 1 0^{24}$ atoms of hydrogen

11.2 L of helium at N.T.P.

Q. Which of the following has the highest mass?

20 g of sulphur

4 mol of carbon dioxide

12×1024 atoms of hydrogen

11.2 L of helium at N.T.P.

(b) Molecular mass of CO2​=44gmol−1 ∴4mol of CO2​=44×4=176g (c) 6.023×1023 atoms of hydrogen has mass =1.008g =12×1024 atoms of hydrogen has mass =20.1g (d) 22.4L of helium at N.T.P. has mass =4g 11.2L of helium at N.T.P. has mass =2g Thus; 4 moles of CO2​ has maximum mass

$12 \times 1 0^{24}$ atoms of hydrogen
