Find the volume of an object that has a density 0f 3.14g/mL and a mass of 87.3g

Chemistry
1 answer:
pav-90 [236]3 years ago
3 0

Answer:

<h3>The answer is 27.80 mL</h3>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density}  \\

From the question

mass = 87.3 g

density = 3.14 g/mL

We have

volume =  \frac{87.3}{3.14}  \\  = 27.8025477...

We have the final answer as

<h3>27.80 mL</h3>

Hope this helps you

This <br> Question please
Marizza181 [45]

Answer:

See detailed explanation.

Explanation:

Hello!

i. In this case, since the given chemical reaction is exothermic due to the negative change in the enthalpy of reaction, we infer that according to the mentioned principle, by lowering the temperature the reaction will shift rightwards and therefore the yield is increased; thus, you need a lower temperature than the specified.

ii. In this case, since the reaction has less moles at the products side, according to the mentioned principle it'd be necessary to rise the pressure in order to increase the yield, since the increase of pressure favors the reaction side with the fewest number of moles.

Best regards!
