Question

The mass of proton is 1.67 X 10-27 kg. how many protons would make 1g.

Answer 1

Answer:

Number of protons make 1 g is $5.98\times 10^{-23}$            

Step-by-step explanation:

Given : The mass of proton is $1.67\times 10^{-27}$ kg.

To find : How many protons would make 1 g?

Solution :

Mass of proton (m) = $1.67\times 10^{-27}$ kg.

Since, 1 kg = 1000 g

$1 kg=10^3 g$

In $1.67\times 10^{-27}kg =1.67\times 10^{-27}\times 10^3g$

$1.67\times 10^{-27}kg =1.67\times 10^{-27+3}g$

$1.67\times 10^{-27}kg =1.67\times 10^{-24}g$

Therefore, 1 proton make $1.67\times 10^{-24}g$

Let N proton make 1 g.

$N=\frac{1}{1.67\times 10^{-24}}$

$N=5.98\times 10^{-23}$

Therefore, Number of protons make 1 g is $5.98\times 10^{-23}$

Answer 2

mass of proton=1.67*10^-27kg

                        =1.67*10^-24g

therefore

1 proton= 1.67*10^-24g

         1g = 1/1.67*10^-24

          1g=0.5988*10^24

          1g=5.988*10^23

therefore,

no of proton in 1 g =5.988*10^23 proton
