a weather balloon holds 2,600 cubic meters of helium. the density of helium is 0.1755 kilograms per cubic meter. how many kilograms of helium does the balloon contain? please round your answer to the nearest whole number. only enter a numerical value in the answer blank. numerical answers expected answer for blank 1:
Answer
Explanation:
Step1: Recall density - mass - volume formula
The formula for density $\rho$ is $\rho=\frac{m}{V}$, where $m$ is mass and $V$ is volume. We want to find $m$, and we know $\rho = 0.1755$ kg/m³ and $V = 2600$ m³.
Step2: Rearrange the formula to solve for mass
Rearranging the formula gives $m=\rho\times V$.
Step3: Substitute the values
$m=0.1755\times2600$. $m = 456.3$ kg.
Step4: Round to the nearest whole number
Rounding 456.3 to the nearest whole number gives 456 kg.
Answer:
456
