Answer:
the other variable is also doubled
Explanation:
direct proportion, same thing has to happen to both variables
Answer:
The pressure will be halved with respect its initial value
Explanation:
Based on Boyle's law, <em>the pressure exerted by a quantity of an ideal gas is inversely proportional to the volume it occupies if the temperature and remains constant</em>
<em />
Thus, if volume of a gas is doubled while the temperature is unchanged, <em>the pressure will be halved with respect its initial value</em>

<span>Molality = moles of solute divided by kilograms of solvent
In this case let’s assume a 100g sample solution:
Since its 10.5% by mass, there is 10.5g glucose. The rest of the 89.5g is water.
Divide the 10.5g glucose by its molar mass (180g) to get the # of moles, which is 0.058moles
So now we have 0.058mole glucose divided by 0.089kilograms of water: the answer is 0.65molal</span>
