How many moles in a 48.5 g sample of CS2?

48,5 g sample of CS2 is the equivalent of 0,637 moles.


How many grams of CS2 are present in 10.00 moles?

For this you need the atomic (molecular) mass of CS2. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. CS2=76.2 grams10.00 moles CS2 × (76.2 grams) = 762 grams CS2


When carbon disulfide is formed from its elements heat is absorbed Calculate the amount of heat in kJ absorbed when 5.66g of carbon disulfied is formed?

The molar mass of carbon disulfide (CS2) is 76.14 g/mol. To calculate the moles of CS2 in 5.66 g, divide the mass by the molar mass: 5.66 g / 76.14 g/mol = 0.074 moles. Since heat is absorbed when CS2 is formed, we know this process is endothermic. You will need to know the molar enthalpy of formation (ΔHf) of carbon disulfide to calculate the amount of heat absorbed.


How many grams of aluminum are needed to react with 192 g of oxygen gas?

First determine the balanced chemical reaction:4Al + 3O2 ---> 2Al2O3Next figure out the number of moles of oxygen you start with by dividing 192 by the molecular weight of oxygen (16 g/mol). Then use the coefficients from the reaction to determine how many moles of Al would need to react with the oxygen to convert all the oxygen and aluminum to aluminum oxide.192 g * (1 mol O / 16 g O) * (4 moles of Al/6 moles of O) = 8 mol of AlFinally multiply by the molecular weight of Aluminum to figure out the mass:8 mol Al * (27 g/mol) = 216 g of Al


5C(s) plus 2SO2(g)CS2(l) plus 4CO(g) How many moles of C are needed to react with 0.480 mole SO2?

The balanced chemical equation is ( 5C(s) + 2SO_2(g) \rightarrow CS_2(l) + 4CO(g) ). According to the stoichiometry of the reaction, 5 moles of carbon (C) react with 2 moles of sulfur dioxide (SO₂). To find the moles of C needed for 0.480 moles of SO₂, use the ratio ( \frac{5 , \text{moles C}}{2 , \text{moles SO}_2} ). Therefore, the moles of C required are ( 0.480 , \text{moles SO}_2 \times \frac{5 , \text{moles C}}{2 , \text{moles SO}_2} = 1.20 , \text{moles C} ).

How many moles are in 100mg of citric acid?

To calculate the number of moles in 100mg of citric acid (C6H8O7), first determine its molar mass by adding up the atomic masses of each element: C(12.01) + H(1.01) + O(16.00) x 7. Convert 100mg to grams (0.1g) and then divide the mass by the molar mass of citric acid to find the number of moles.
