To calculate the number of moles in 175.24 g of strontium, divide the given mass by the molar mass of strontium (87.62 g/mol). This gives you 175.24 g / 87.62 g/mol = 2 moles of strontium.
To find the number of moles of strontium chloride in 20 mL of a 0.2 M solution, you can use the formula: moles = concentration (M) × volume (L). First, convert 20 mL to liters, which is 0.020 L. Then, calculate the moles: 0.2 moles/L × 0.020 L = 0.004 moles of strontium chloride.
The formula unit for strontium chloride is StCl2 and therefore contains 3 atoms, one of strontium and two of chlorine.
97,5 g of oxygen is equal to 5,416 moles.
0.377 grams of Kr is equal to 0,0045 moles.
15 moles of 02 equal 480 g.
0,17 moles of stronium is equal to 1,02376394569.10e23 atoms.
