Question 115(i)

Express the following in standard form.The mass of a proton in grams is$\frac{1673}{1000000000000000000000000000}$

Answer 1

Given, the mass of a proton in gram $=\frac{1673}{1000000000000000000000000000}$
Standard form $=\frac{1673}{{10}^{27}}=1673\times {10}^{-27}g[a^{-m}=\frac{1}{a^m}]=1.673\times {10}^3\times {10}^{-27}g=1.673\times {10}^{3+(-27)}=1.673\times {10}^{-24}g$
