Question

calculating mass
while participating in a blood drive at school, keona learns that blood has a density of 1.06 g/ml. she donates one
pint of blood, which is equal to 473.176 ml.
what is the mass of the blood keona donates, to the nearest hundredth of a gram?
the mass of the blood keona donates is g

Explanation:

Step1: Recall the density formula

Density formula is \(d=\frac{m}{V}\), where \(d\) is density, \(m\) is mass, and \(V\) is volume. We can rewrite it for mass as \(m = d\times V\).

Step2: Substitute the given values

Given \(d = 1.06\space g/mL\) and \(V=473.176\space mL\). Then \(m=1.06\times473.176\).

Step3: Round to the nearest hundredth

Rounding \(501.56656\) to the nearest hundredth. The digit in the thousandth place is \(6\), so we round up the hundredth place digit. So \(m\approx501.57\)

Answer:

\(501.57\)
