Answer:

2.67 g/mL

Explanation:

Initial Volume of water = 10.0 mL

Final Volume pf water = 15.46 mL

Mass = 14.74g

Density = Mass / Volume of aluminium

Volume of aluminium = Final Volume of water - Initial Volume of water = 15.46 - 10 = 5.46mL

Density = 14.74 / 5.46 = 2.67 g/mL

Explanation:

In an alpha emission, an alpha particle is ejected from a large nucleus. An alpha particle is simply a helium nucleus (atomic number is 2 and mass number is 4) so that means that the atomic number of the emitting nucleus decreases by 2 and its mass number decreases by 4.

At 6 atmosphere pressure, the volume of a gas is 1200 ml. What pressure is
NeTakaya

Answer:

<h2>36 atm </h2>

Explanation:

The pressure required can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

Since we are finding the required pressure

P_2 =  \frac{P_1V_1}{V_2}  \\

From the question we have

P_2 =  \frac{6 \times 1200}{200}  =  \frac{7200}{200}  =  \frac{72}{2}  \\

We have the final answer as

<h3>36 atm</h3>

Hope this helps you
