How do you prepare 30 percent of NaOH?
To prepare a 30% NaOH solution, you would mix 30 grams of NaOH with enough water to make 100 grams of final solution. Be sure to use caution when handling NaOH as it is a caustic substance and can cause skin and eye irritation.
What is the percent of a composition of a compound containing 8.6g of Be and 52.4g of I?
To find the percent composition of each element in the compound, you first calculate the molar mass of Be (9.01 g/mol) and I (126.90 g/mol). Then, calculate the percent composition of each element by dividing the mass of the element by the total molar mass of the compound and multiplying by 100. The percent composition of Be is 5.14% and the percent composition of I is 94.86%.
What is the percent composition for 29.0 g of Argon combine completely with 4.30 g of Sulfur?
To find the percent composition, first calculate the total mass by adding the masses of Argon and Sulfur. Then, determine the percent composition of each element by dividing the mass of that element by the total mass and multiplying by 100. In this case, the percent composition of Argon is about 87.1%, and the percent composition of Sulfur is about 12.9%.
