Since we are given the density and volume, then perhaps we can determine the amount in terms of the mass. All we have to do is find the volume in terms of cm³ so that it will cancel out with the cm³ in the density. The conversion is 1 ft = 30.48 cm. The solution is as follows:
V = (14 ft)(15 ft)(8 ft)(30.48 cm/1 ft)³ = 0.0593 cm³
The mass is equal to:
Mass = (0.00118g/cm³)(0.0593 cm³)
Mass = 7 grams of HCN

Answer:
is the no. of electrons
Explanation:
Given:
- quantity of charge transferred,
<u>No. of electrons in the given amount of charge:</u>
As we have charge on one electron 
so,
is the no. of electrons
- Now if each water molecules donates one electron:
Then we require 
molecules.
<u>Now the no. of moles in this many molecules:</u>
where
Avogadro No.
- We have molecular mass of water as M=18 g/mol.
<u>So, the mass of water in the obtained moles:</u>
where:
m = mass in gram
Answer:
1.991 × 10^(8) N/m²
Explanation:
We are told that its volume increases by 9.05%.
Thus; (ΔV/V_o) = 9.05% = 0.0905
To find the force per unit area which is also pressure, we will use bulk modulus formula;
B = Δp(V_o/ΔV)
Making Δp the subject gives;
Δp = B(ΔV/V_o)
Now, B is bulk modulus of water with a value of 2.2 × 10^(9) N/m²
Thus;
Δp = 2.2 × 10^(9)[0.0905]
Δp = 1.991 × 10^(8) N/m²
