Question 35
Express each of the following in kilograms
(a) $5.84\times {10}^{-3}mg$
(b) $58.34g$
(c) $0.584g$
(d) $5.873\times {10}^{-21}g$

Answer 1

(a) ${10}^{6}mg=1kg$
$5.84\times {10}^{-3}mg$=$\frac{1\times 5.84\times {10}^{-3}}{{10}^6}$=$5.84\times {10}^{-9}kg$

(b) ${10}^{3}g=1kg$
$58.34g$ = $\frac{1\times 58.34}{{10}^3}$ = $5.834\times {10}^{-2}kg$

(c) ${10}^{3}g=1kg$
$0.584g$ = $\frac{1\times 0.584}{{10}^3}$ = $5.84\times {10}^{-4}kg$

(d)${10}^{3}g=1kg$
$5.873\times {10}^{-21}g$=$\frac{1\times 5.873\times {10}^{-21}}{{10}^3}$= $5.873\times {10}^{-24}kg$
