Question

1. calculate a weather balloon is inflated to a volume of 2.2 × 10³ l with 374 g of helium. what is the density of helium in grams per liter?

Explanation:

Step1: Recall density formula

Density $
ho=\frac{m}{V}$, where $m$ is mass and $V$ is volume.

Step2: Identify given values

$m = 374$ g, $V=2.2\times 10^{3}$ L.

Step3: Calculate density

$
ho=\frac{374}{2.2\times 10^{3}}=\frac{374}{2200}= 0.17$ g/L.

Answer:

$0.17$ g/L
