Final answer:
To calculate the mass of salt in 12 teaspoons, multiply the amount per teaspoon (5.00 grams) by the number of teaspoons (12), resulting in 60 grams of salt.
Step-by-step explanation:
The question asks to find the total mass of salt in grams if 12 teaspoons of salt are used and it is known that 1.00 teaspoon of salt weighs 5.00 grams. To find the total mass, use the given conversion factor:
1.00 teaspoon = 5.00 grams
Therefore, for 12 teaspoons:
12 teaspoons × 5.00 grams/teaspoon = 60 grams
This calculation assumes that the density of salt is constant, which is a reasonable approximation for such a calculation.
