A recipe for spaghetti sauce requires 2.5 cups of tomato sauce. If only metric measures are available, how many milliliters of tomato sauce are needed? (1qt = 4 cups, 1q = 946 mL)

6.0 × 10² mL

Explanation:

Step 1: Given data

A recipe for spaghetti sauce requires 2.5 cups of tomato sauce.

Step 2: Calculate the US Quarts (qt) corresponding to 2.5 cups of tomato sauce

We will use the relationship 1 qt = 4 cups.

2.5 cups × (1 qt/4 cups) = 0.63 qt

Step 3: Calculate the milliliters (mL) corresponding to 0.63 qt of tomato sauce

We will use the relationship 1 qt = 946 mL.

0.63 qt × (946 mL / 1 qt) = 6.0 × 10² mL

if you mean hydrogen and oxygen then water is the product

the answer would be a
