Answer:
The objects mass is 84, 105 g. See the explanation below, please.
Explanation:
We use the formula:
Density= mass/volume
Mass= Density x volume =0.801 g/mL x 105 mL = 84, 105 g
Because it is a solid material, it is known as a dry lubricant. This is useful in applications where “wet” lubricants, such as oil, cannot be used<span>. </span>Graphite<span> is the only non-metal element that is a good conductor of electricity. Natural </span>graphite<span> is </span>used <span>mostly in what are called refractory applications.</span>
To make the conversion we must take into account the relationship between kBq and microcuries. Both are units that represent radioactivity activity. The relationship is:
1 kilobecquerel (kBq) = 0.027027027 microcurie
Therefore, 2.6kBq will be equal to:

Answer= That activity in microcuries will be 0.070 microcuries
6.04 x 10^14. See attached work.
