In an experiment, students were given an unknown mineral. The unknown mineral was placed in 150 ml of water. Once in the water,
Dahasolnce [82]

Answer:

<h2>15 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

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

But from the question

volume = final volume of water - initial volume of water

volume = 165 - 150 = 15 mL

We have

density =  \frac{225}{15}  = 15 \\

We have the final answer as

<h3>15 g/mL</h3>

Hope this helps you

Two sealed flasks each have a volume of 2.0 liters. Flask A contains N, O gas and Flask B contains H, gas both at 1
barxatty [35]

Answer:

Each gas have same number of molecules.

Explanation:

According to Avogadro law,

Equal volume of all the gases at same temperature and pressure have equal number of molecules.

Mathematical expression:

V ∝ n

V = Kn

V/n = K

k = constant

V = volume of gas

n = number of moles of gas

when volume change is changed from v1 to v2 and number of moles from n1 to n2 this law can be written as,

V1 / n1 = V2 /n2

This state that by increasing the number of moles of gas volume also goes to increase.
