Answer: 1.7L
Explanation:
Original volume of nitrogen gas (V1) = 3.4L
Original temperature of nitrogen gas (T1) = 400K
New volume of nitrogen gas (V2) = ?
New temperature of nitrogen gas (T2) = 200K
Since volume and temperature are given while pressure is held constant, apply the formula for Charle's law
V1/T1 = V2/T2
3.4L/400K = V2/200K
To get the value of V2, cross multiply
3.4L x 200K = 400K x V2
680L•K = 400K•V2
Divide both sides by 400K
680L•K /400K = 400K•V2/400K
1.7L = V2
Thus, the final volume of the nitrogen gas is 1.7 liters
Answer:
There are 0.301 moles of N2 gas in 6.75 liters of N2 gas.
Explanation:
Given,
Volume of N2 gas = 6.75 L
We know,
At STP,
Number of moles = 
[Here 22.4 liter is the molar volume of any gas at STP]
= 
= 
∴There are 0.301 moles of N2 gas in 6.75 liters of N2 gas.
Answer:
5.27*10^23 (rounded to 3 significant figures)
Explanation:
The amount of molecules in one mole of anything is equal to Avogadro's number: 6.022×10^23
To find the number of moles of NaOH in 35 grams of it, do 35 divided by the molar mass (39.997): 35/39.997=0.87506562 moles of NaOH
To find the number of molecules, multiply the moles of NaOH by Avogadro's number: 0.87506562×(6.022×10^23)=5.26964522*10^23
Most likely d because water is being used for energy, therefore releasing water vapo. Also by process of elimination, that´s the one that makes sense lol.
Answer:
It would have 23 chromosomes.
Explanation:
A Diploid is a cell or organism that has paired chromosomes, one from each parent.
In humans, cells other than sex cells, a diploid will have 23 pairs of chromosomes.
