The mass of a mole of proton and electron is

Question

The mass of a mole of proton and electron is (A)  6.023× 1023g  (B) 1.008 g and 0.55 mg (C)  9.1× 10-28kg  (D) 2 g

Tardigrade Admin · Accepted Answer

Mass of a proton =1.673 × 10-24 g ∴ Mass of one mole of proton =1.673 × 10-24 × 6.02 × 1023 =10.07 × 10-1 =1.008 g Mass of an electron =9.1 × 10-28 g ∴ Mass of one mole of electron =9.1 × 10-28 × 6.02 × 1023 =54.78 × 10-5 g =0.55 mg

Q. The mass of a mole of proton and electron is

$6.023 \times 1 0^{23} g$

$1.008 g$ and $0.55 m g$

$9.1 \times 1 0^{- 28} k g$

$2 g$

Q. The mass of a mole of proton and electron is

6.023×1023g

1.008g and 0.55mg

9.1×10−28kg

2g

Mass of a proton =1.673×10−24g ∴ Mass of one mole of proton =1.673×10−24×6.02×1023 =10.07×10−1 =1.008g Mass of an electron =9.1×10−28g ∴ Mass of one mole of electron =9.1×10−28×6.02×1023 =54.78×10−5g=0.55mg

$6.023 \times 1 0^{23} g$

$1.008 g$ and $0.55 m g$

$9.1 \times 1 0^{- 28} k g$

$2 g$
