Final answer:
To make saltwater, when 10 grams of water are added to 5 grams of salt, the total mass of the saltwater solution made is 15 grams, which is the sum of the mass of the water and salt.
Step-by-step explanation:
When 10 grams of water are added to 5 grams of salt (NaCl), the total mass of the saltwater solution made will be the sum of the mass of the water and the mass of the salt. Since mass is a conserved quantity and we are ignoring any potential changes due to temperature or chemical reactions that would produce a gas, the combined mass is simply the addition of the two masses.
To find the total mass of the saltwater solution, we do the following calculation:
Mass of water = 10 g
Mass of salt (NaCl) = 5 g
Total mass of saltwater = Mass of water + Mass of salt
Total mass of saltwater = 10 g + 5 g
Total mass of saltwater = 15 grams
Thus, the total mass of the saltwater solution formed by combining these amounts of salt and water is 15 grams.
