Moles of Oxygen they took in : C. 2.42
<h3>Further explanation</h3>
The gas equation can be written
where
P = pressure, atm
V = volume, liter
n = number of moles
R = gas constant = 0.08205 l.atm / mol K
T = temperature, Kelvin
P=1000 kPa
V = 6 L
T = 298 K
moles of Oxygen :
Answer:
The empirical formula for this compound is thus CH2.
Explanation:
Answer: False
Explanation: if something is in high resolution it has clear details
Answer:
Explanation:
The formula of density is:
If the formula is rearranged for volume, it becomes:
The mass of the platinum is 38.5 grams.
The density is 21.5 grams per cubic centimeter.
Substitute the values into the formula.
Divide. Note that the grams (g) will cancel each other out.
Round to 2 decimal places (hundredth place). The 0 in the thousandth place tells us to leave the 9 in the hundredth place.
The volume is about <u>1.79 cubic centimeters.</u>
