2Mg + O2 ==> 2MgO Balanced Equation4.03 g Mg x 1 mole Mg/24.3 g = 0.166 moles Mg present in 4.03 g Mg.moles O2 required = 0.166 moles Mg x 1 mole O2/2 moles Mg = 0.083 moles O2 needed.At STP 1 mole occupies 22.4 L, thusVolume of O2 required = 0.083 moles x 22.4 L/mole = 1.56 L x1000 ml/L = 1859 mlsSince 4.03 g has only 3 significant figures, the correct answer should be 1860 milliliters.

The balanced reaction for the decomposition of potassium chlorate (KClO3) is: 2 KClO3 -> 2 KCl + 3 O2 From the reaction, 2 moles of KClO3 produce 3 moles of O2. Calculate the moles of KClO3 in 6.125g using its molar mass. Convert moles of KClO3 to moles of O2. Use the ideal gas law to find the volume of O2 at STP (22.4 L/mol).
No, one mole of each, having the same VOLUME (about 22.4 L at STP), differ though in their masses: 32 g/mol for O2 and 28 g/mol for N2 So their densities (mass per volume) also differ in the same way: 1.43 g/L and 1.25 g/L respectively, at STP.
The balanced equation for the reaction is: 2SO2 + O2 -> 2SO3. Therefore, 1 mole of O2 is needed to react with 2 moles of SO2 to form 2 moles of SO3. So for 200 moles of SO2, you would need 100 moles of O2. At STP, 1 mole of any gas occupies 22.4 L, so the volume of O2 needed would be 2240 L (100 moles x 22.4 L).

1 mole of gas occupies 22.4 liters at STP. Therefore 3.5/22.4 = 0.15625 moles of SO2. There are thus 0.15625 moles of O2 needed to react with solid sulfur because S + O2 ---->SO2. 0.15625 moles of oxygen occupies 0.15625 x 22.4 liters = 3.5 liters O2 required.

At standard temperature and pressure (STP), one mole of any ideal gas occupies 22.4 liters. To find the number of moles of O2 in 5.33 L, you can use the formula: moles = volume (L) / molar volume (L/mol). Thus, moles of O2 = 5.33 L / 22.4 L/mol, which is approximately 0.238 moles.
The balanced reaction for the decomposition of potassium chlorate (KClO3) is: 2 KClO3 -> 2 KCl + 3 O2 From the reaction, 2 moles of KClO3 produce 3 moles of O2. Calculate the moles of KClO3 in 6.125g using its molar mass. Convert moles of KClO3 to moles of O2. Use the ideal gas law to find the volume of O2 at STP (22.4 L/mol).
Because oxygen gas (O2) has a molar mass of 32g/mol, 11.3 g * 1/32 mol/g gives about .35 moles. An ideal gas has a volume of 22.4 L/mol at STP, so 11.3 g O2 would have a volume of 7.91 L at STP.
No, one mole of each, having the same VOLUME (about 22.4 L at STP), differ though in their masses: 32 g/mol for O2 and 28 g/mol for N2 So their densities (mass per volume) also differ in the same way: 1.43 g/L and 1.25 g/L respectively, at STP.
The balanced equation for the reaction is: 2SO2 + O2 -> 2SO3. Therefore, 1 mole of O2 is needed to react with 2 moles of SO2 to form 2 moles of SO3. So for 200 moles of SO2, you would need 100 moles of O2. At STP, 1 mole of any gas occupies 22.4 L, so the volume of O2 needed would be 2240 L (100 moles x 22.4 L).
The reaction : Mg + O2-----------> MgO The balanced reaction : 2 Mg + O2-----------> 2 MgO that is 2 moles of Mg reacts with one mole of oxygen gas. moles of Mg reacted = 12 g / 24 g mol-1=0.5 mol. Thus the no. of mol of O2 reacted = 0.5 mol /2 =0.25 mol If the gas is at standard temperature and pressure, then Volume of 1 mol of O2 gas = 22.4 dm3 Volume of 0.25 mol of O2 gas = 22.4 x 0.25 dm3= 5.6 dm3 the volume of oxygen that will be used to react completely with 12 g Mg =5.6 dm3 (provided that the gas is at the standard conditions.)
To find the weight of 2350 L of O2 gas at STP, you would first need to calculate the moles of gas using the ideal gas law. Then, use the molar mass of O2 to convert moles to grams. The molar mass of O2 is 32 g/mol, so you would multiply the moles by 32 g/mol to find the weight in grams.
At standard temperature and pressure (STP), one mole of a gas is 22.4L. So, in order to determine how many moles of O2 are in 30L, you do the following: multiply 30L O2 x 1mol O2/22.4L O2, which equals 1.34mol O2.
