35.2 grams C6H8O (1 mole C6H8O/96.124 grams)(6.022 X 1023/1 mole C6H8O)
= 2.21 X 1023 atoms of vitamin C
===========================
To find the weight of an object in Newtons, you need to multiply its mass in kilograms by the acceleration due to gravity (9.81 m/s^2). So, first convert the mass of the object from grams to kilograms: 352g = 0.352kg Now, multiply the mass in kilograms by the acceleration due to gravity: 0.352kg * 9.81 m/s^2 ≈ 3.46 N Therefore, the weight of a 352g object is approximately 3.46 Newtons.
Considering that the moon is about 1/4 of the size of the planet Earth, its gravity is aroung 83.3% (or 5/6) less that of our planet, therefore, if "weight" is the measure of the gravitational pull between two objetcs, 352g of an object on Earth, it will weight 58.4 g on the surface of the moon.
I think you're missing an exponent on the number of molecules. Otherwise, it's just a 2-step conversion: molecules to moles, then moles to mass, based on the compound's molar mass of 352g/mol.
