Question 5 (1 point) Determine the mass in grams of (5.319x10^25) helium atoms. He = 4.000 g/mol Use 6.022x1023 for Avogadro's number. Enter your answer rounded to the correct number of significant figures AND put it into scientific notation. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: x10 units Answer
Question 6 (1 point) A protein has an empirical formula of C3H3O4. Proteins can have a very high molecular mass. In this case, the molecular mass for the protein is 2,062.18 g/mol. What number do all the subscripts in the empirical formula need to be multiplied by to determine the molecular formula of the compound? C = 12.01 g/mol H = 1.01 g/mol O 16.00 g/mol = Do not use significant figures. Round your answer to a whole number (no decimals)
