Question

The table below classifies 103 elements as metal, metalloid, or nonmetal and as solid, liquid, or gas at standard temperature and pressure.

	Solids	Liquids	Gases	Total
Metals	77	1	0	78
Metalloids	7	0	0	7
Nonmetals	6	1	11	18
Total	90	2	11	103

What fraction of all solids and liquids in the table are metalloids?

• A. $\frac{7}{92}$
• B. $\frac{7}{103}$
• C. $\frac{7}{90}$
• D. None

Answer 1

Answer: (A)

$\frac{7}{92}$

Solids in Metalloids $=7$

Liquids in Metalloids $=0$

Total solids and metal in Metalloids $=7+0=7$

$\Rightarrow$ Total solids and liquids $=90+2=92$

$\Rightarrow$ Required fraction $=\frac{7}{92}$
