Question

What is the value of 500 Mg in kilogram?

• A. 5 $\times$ ${10}^6$ kg
• B. 5 $\times$ ${10}^5$ kg
• C. 5 $\times$ ${10}^7$ kg
• D. 5 $\times$ ${10}^4$ kg

Answer 1

The correct option is B

5 $\times$ ${10}^5$ kg

500 Mg is given to us. Mega means ${10}^6$
$\therefore$ 500 $\times$ ${10}^6$ g = 5 $\times$ ${10}^8$ g = 5 $\times$ ${10}^5$ $\times$ ${10}^3$ g
But ${10}^3$is kilo

$\therefore$ 500 Mg = 5 $\times$ ${10}^5$ kg
