Answer:
500N/m²
Explanation:
The Pressure can be calculated using the formula:
P = F/A
Where;
F = force (N)
A = Area (m²)
Based on the information provided in the question, F = 30N, A = 0.06m²
P = F/A
P = 30/0.06
P = 500N/m²
This would be 1.22 x 10^1
You simply move the decimal.

Answer:
5.2g copper (Cu) => 0.082 moles copper (2 sig.figs.)
Explanation:
mole conversions:
grams to moles => divide by formula wt.
moles to grams => multiply by formula wt.
gas volumes to moles => divide volume by 22.4Liters/mole (STP conditions only)
This problem:
mass to moles => divide by formula wt.
mass = 5.2g = 5.2g/63.5g/mole = 0.082 moles copper (2 sig.figs.)
Answer:
Lithium chloride is a white solid hygroscopic soluble in water.
Doesnt the number of carbon atoms stay the same.
Though the weight of carbon in 1.5g is 1.24g.
This is because the RAM of C4 is 48.
The RFM of C4H10 is 58. Therefore, 48/58 is carbon in butane.
48/58 x 1.5 = 1.24g
