please answer this properly and use the units that are asked in the answer please don't use anything else ASAp 5c please read the last bold line tooASAP Express the number of moles to three significant figures. Creating an equation using the expressions including r and yNow if x is the initial mass of magnesium and y is the initial mass of aluminum, the total number of moles of hydrogen gas produced, n, can be expressed asn= 0.0411x +0.0556y.If the total mass of the two metals is 0.250 g, then x +y = 0.250, and therefore x = 0.250 – y.Substitute for æ in the first equation to express n in terms of y.n = 0.0411(0.250 – y) +0.0556yThe value of n can be found using the ideal gas law.Part CTaking into account the vapour pressure of water, how many moles of hydrogen gas, n, are present in 303 mL at 752 Torr and 29 °C?The value of the gas constant R is 0.08314 L bar mol-1 K-1 You may also find the conversion factors1 bar= 750 Torr and Tx = Tc +273 useful.Express the number of moles to three significant figures.• View Available Hint(s)?n =mol

Creating an equation using the expressions including z and y Now if z is the initial mass of magnesium and y is the initial mass of aluminum, the total number of moles of hydrogen gas produced, n, can be expressed as n= 0.0411z + 0.0556y. If the total mass of the two metals is 0.250 g, then æ +y = 0.250, and therefore a = 0.250 – y. Substitute for æ in the first equation to express n in terms of y. n= 0.0411(0.250 – y) +0.0556y The value of n can be found using the ideal gas law. Part C Taking into account the vapour pressure of water, how many moles of hydrogen gas, n, are present in 303 mL at 752 Torr and 29 °C? The value of the gas constant Ris 0.08314 L bar mol-1 K1.
