Express each of the following in standard form: |
(a) The mass of a proton in gram is \[\frac{1673}{1000000000000000000000000000}\] |
(b) A Helium atom has a diameter of 0.000000022 cm. |
Answer:
(a) \[\frac{1673}{1000000000000000000000000000}\] \[=\frac{1.673\times {{10}^{3}}}{{{10}^{27}}}\] \[=\text{ }1.673\text{ }\times \text{ }{{10}^{24}}\] gm (b) \[0.000000022=2.2\times {{10}^{8}}\] cm
