Answer:
To find the number of milligrams in 1.2 cups of water, you need to first convert the volume in cups to volume in milliliters. 1 cup is equivalent to approximately 236.59 mL. Therefore, 1.2 cups is equal to approximately 283.91 mL. To find the number of grams in this volume, you can use the density of water, which is 1.0 g/mL. Multiply the volume in mL by the density in g/mL to get the mass in grams. So, 1.2 cups of water is approximately 283.91 mL * 1.0 g/mL = 283.91 grams. To convert this to milligrams, multiply by 1000 (1 gram = 1000 milligrams), so 283.91 grams * 1000 milligrams/gram = 283,910 milligrams
To find the number of grams of fat in a 112g sample of ground beef that is 12.5% fat by mass, you need to use the percentage of fat by mass to find the mass of fat in the sample. Multiply the total mass of the sample (112g) by the percentage of fat by mass (12.5%) to find the mass of fat. So, 112g * 12.5% = 14g of fat.
