Answer:
The answer is 39.99711. We assume you are converting between grams NaOH and mole. You can view more details on each measurement unit: molecular weight of NaOH or mol This compound is also known as Sodium Hydroxide.
One lithium (Li) atom can combine with one fluorine (F) atom. Together, they make the formula LiF. Fluorine has seven electrons of it's own. Lithium gives up its one electron to make both atoms happy. So the fluorine atom has eight electrons, and a filled outer shell.

Equation for decomposition is as follow,
2 NH₄ClO₃ → 3 O₂ + 2 NH₄<span>Cl
According to eq.
</span>
67.2 L (3 mole) off O₂ is produced by = 202.98 g (2 moles) NH₄ClO₃
So,
200 L of O₂ will be produced by = X g of NH₄ClO₃
Solving for X,
X = (202.98 g × 200 L) ÷ 67.2 L
X = 604.10 g of NH₄ClO₃
The formula for molality---> m = moles solute/ Kg of solvent
the solute here is NH₃ because it's the one with less amount. which makes water the solvent.
1) let's convert the grams of NH₃ to moles using the molar mass
molar mass of NH₃= 14.0 + (3 x 1.01)= 17.03 g/ mol
15.0 g (1 mol/ 17.03 g)= 0.881 mol NH₃
2) let's convert the grams of water into kilograms (just divide by 1000)
250.0 g= 0.2500 kg
3) let's plug in the values into the molality formula
molality= mol/ Kg---> 0.881 mol/ 0.2500 kg= 3.52 m
