I agree
Explanation:
For scientists working in classified areas, collaboration with university programs and researchers provides opportunities to expand and strengthen their science through the conduct of peer-reviewed, open literature research.
Answer : The image is attached below.
Explanation :
For
:
Molar mass, M = 48 g/mol
Mass, m = 24 g
Moles, n = 
Number of particles, N = 
For
:
Molar mass, M = 17 g/mol
Mass, m = 170 g
Moles, n = 
Number of particles, N = 
For
:
Molar mass, M = 38 g/mol
Mass, m = 38 g
Moles, n = 
Number of particles, N = 
For
:
Molar mass, M = 44 g/mol
Moles, n = 0.10 mol
Mass, m = 
Number of particles, N = 
For
:
Molar mass, M = 46 g/mol
Moles, n = 0.20 mol
Mass, m = 
Number of particles, N = 
For
:
Molar mass, M = 20 g/mol
Number of particles = 
Moles, n = 
Mass, m = 
For
:
Molar mass, M = 44 g/mol
Number of particles = 
Moles, n = 
Mass, m = 
For unknown substance:
Number of particles = 
Mass, m = 8.5 g
Moles, n = 
Molar mass, M = 
The substance is
.
According to Boyle's law, Volume is indirectly proportional to the pressure.
So, P1V1 = P2V2
Substitute the known values,
1 * 50 = 3 * V2
V2 = 50/3 = 16.67 mL
In short, Your Answer would be: 16.67 mL
Hope this helps!
Answer:
2.94 x 10⁻¹⁴L
Explanation:
To solve this problem, we have to assume that the condition of this water is at standard temperature and pressure, STP.
At STP;
1 mole of gas have a volume of 22.4L
So, let us find the number of moles of this water first;
6.02 x 10²³ molecules can be found in 1 mole of a substance
7.89 x 10⁸ molecules will contain
= 1.31 x 10⁻¹⁵mole of water
So;
Volume of water = 22.4 x 1.31 x 10⁻¹⁵ = 2.94 x 10⁻¹⁴L
Answer:
0.625 moles MgCl₂
Explanation:
Since you were given a molarity value and volume, you should use the molarity equation to find moles. The equation looks like this:
Molarity (M) = moles / volume (L)
To find moles, you need to (1) convert mL to L (by dividing by 1,000) and then (2) plug the numbers into the formula and simplify to find moles. The final answer should have 3 sig figs as the lowest amount of sig figs in a given value is 3.
<u>Step 1:</u>
650.0 mL / 1,000 = 0.6500 L
<u>Step 2:</u>
Molarity = moles / volume
0.962 M = moles / 0.6500 L
(0.962 M) x (0.6500 L) = moles
0.625 = moles
