Answer:

The density of the sample is 11.8 g/mL.

Explanation:

We are given an unknown sample with a mass of 23.5 g and a volume of 2.00 mL and we want to determine its density.

Recall that density is given by:

\displaystyle \rho = \frac{m}{V}

Where ρ is the density, <em>m</em> is the mass, and <em>V</em> is the volume.

Substitute 23.5 g for <em>m</em> and 2.00 mL for <em>V</em> and evaluate:

\displaystyle \begin{aligned} \rho & = \frac{m}{V} \\ \\ & = \frac{(23.5\text{ g})}{(2.00 \text{ mL})}\\ \\  & = 11.8 \text{ g/mL}\end{aligned}

Hence, the density of the sample is 11.8 g/mL.

Answer:

mass=23.5g

volume=2.88ml

Explanation:

But density= mass/volume

23.5/2.88

=8.15kgm^-3

Scientists can tell recycling reduces atmospheric emissions by knowing which of the following? o it takes more Btu to manufactur
Dmitriy789 [7]

Answer:

According to the Environmental Paper Network's Paper Calculator, it takes about 32 million BTUs of energy to produce 1 ton of virgin paper fiber. To produce 1 ton of recycled paper, it takes about 22 million BTUs.

so the answer could be it takes less Btu to manufacture recycled products than new ones
