Calculate the volume in Liters of 15 moles of Neon gas (at STP)
Archy [21]
Step by step solution:

Its given;
Moles of neon at STP is 15 mol
We are required to calculate the volume;
According to molar gas volume, 1 mole of a gas occupies a volume of 22.4 liters at STP.
That is, 1 mole of a gas = 2.4 L
Therefore;
1 mole of Neon gas = 22.4 L

Volume = Moles of the gas × molar gas volume
= 15 mol × 22.4 L/mol
= 336 L

dalvyx [7]

Answer:

B. 2g

Explanation:

So first you have to find the mole to mole ratio then convert it to grams if that makes sense. So the mole to mole ratio is 2 ammonia to 3 hydrogen gas. So then after you do that conversion you can solve for grams then. Sorry I am not that great at explaining.

How many grams of AgNO3 are needed to prepare a 75.00 mL solution that is 6.5% (m/v)?
FrozenT [24]

Answer:

Volume of AgNO₃ = 4.9 ml (Approx)

Explanation:

Given:

Total solution = 75 ml

Volume of AgNO₃ = 6.5%

Find:

Volume of AgNO₃

Computation:

Volume of AgNO₃ = Total solution x Volume of AgNO₃

Volume of AgNO₃ = 75 x 6.5%

Volume of AgNO₃ = 4.875

Volume of AgNO₃ = 4.9 ml (Approx)
