How many moles are present in 205 g of helium?
To find the number of moles present in 205 g of helium, we need to use the molar mass of helium, which is approximately 4 g/mol. Divide the given mass by the molar mass to get the number of moles. In this case, 205 g / 4 g/mol = 51.25 moles of helium.
How many moles are present in 205g of helium?
To calculate the number of moles, you need to divide the given mass by the molar mass of helium. The molar mass of helium is approximately 4 g/mol. Therefore, the number of moles in 205g of helium would be 205g / 4g/mol = 51.25 mol.

How many grams of NaOH are needed to prepare 250mL of 205 M of NaOH?
To calculate the grams of NaOH needed, you first need to find the moles of NaOH required: 205 M concentration means 205 moles/L. So, for 250 mL (0.25 L), you multiply 0.25 L by 205 moles/L to get 51.25 moles. Finally, using the molar mass of NaOH (40 g/mol), you can convert moles to grams by multiplying 51.25 moles by 40 g/mol to find you need 2050 grams of NaOH.
How many moles of Ba(OH)2 are present in 205mL of 0.600M Ba(OH)2?
To find the number of moles of Ba(OH)2 present, we first need to calculate the amount of substance using the provided concentration and volume. This is done using the formula: moles = concentration (mol/L) x volume (L). Converting 205 mL to liters (205 mL = 0.205 L) and plugging in the values, we get moles = 0.600 mol/L x 0.205 L = 0.123 moles of Ba(OH)2.
