Density is the measure of how much mass is contained in a given volume.
Answer: V= 4.2L
Explanation: To solve for the new volume we use Boyle's Law.
P1V1 = P2V2
Derive for V2 the new volume.
V2 = P1V1 / P2
V2 = 1.8 atm x 2.8 L / 1.2 atm
= 4.2 L
When adjusted for any changes in δh and δs with temperature, the standard free energy change δg∘t at 2400 k is equal to 1.22×105j/mol, then the equilibrium constant at 2400 k is 2.21×10−3. The answer to the statement is 2.21×10−3.
Answer:
50 atoms are in mole aluminium
Answer:
The answer to your question is 0.1595 mg of Oxygen
Explanation:
Data
K = 38.67 g
N = 13.86 g
O = ?
Mass of oxygen in 336 mg
Process
1.- Convert 336 mg to grams
1000 mg ----------------- 1 g
336 mg ---------------- x
x = (336 x 1)/1000
x = 0.336 g of sample
2.- Calculate the mass of oxygen in 100g
Mass of oxygen = 100g - 38.67g - 13.86g
= 47.47 g
This means that oxygen represents 47.47% of the sample
3.- Calculate the grams of Oxygen in 0.336 mg.
Mass of Oxygen = (0.336)(0.4747)
Mass of Oxygen = 0.1595 mg
