The volume of the hydrogen gas would be 116.022 L
<h3>Density</h3>
The density of an object is a measure of how heavy the object is.
Mathematically, the density of an object is given by:
Density = mass/volume.
Thus, given 2 out of the 3 variables that make up the equation, the unknown variable can be calculated.
In this case, the mass and the density of hydrogen were given as 10.326 g and 0.089 g/L respectively.
Therefore, we need to find the volume by making it the subject of the formula from the equation above.
Volume = mass/density.
10.326/0.089 = 116.022 L
This means that the volume of the hydrogen gas is 116.022 L

B-10 = 19.9%
B-11 = 80.1%
Abundance of B10 = x
Abundance of B11= y
You know x+y = 1 because there are only the 2 isotopes.
Y= 1-x
10.01294x + 11.00931 (1-x) = 10.811
10.01294x + 11.00931 - 11.00931x = 10.811 - 0.99016x = -0.198
X = 0.200
Check:
10.01294(0.2) + 11.00931 (0.8) = 10.81
20% B10. 80% B11
Answer:
group ten period four. that's the answer
Molality is defined as the number of moles of solute in 1 kg of solvent .
the mass of water - 512.85 ml x 0.975 g/ml = 500 g
number of moles of solute in 500 g of water - 171 g / 342.30 g/mol = 0.500 mol
the number of sucrose moles in 500 g of water - 0.500 mol
therefore number of sucrose moles in 1 kg water - 0.500 mol / 0.500 kg = 1.00
molality of solution - 1.00 M
