Helium exists as a monatomic noble gas. Its Atomic Mass is 4.0 as can be obtained from the Periodic Table. The amount of helium in a 205g pure sample is given by 205/4.0 which equates to roughly 51 moles.
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.
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.

2.05 meters is equivalent to 205 centimeters, as there are 100 centimeters in 1 meter.
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.
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.
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.
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.
