Final answer:
To find the weight of the marshmallow, we need to multiply its density by its volume after converting the volume to cubic centimeters. The weight of the large marshmallow is approximately 11.8716 grams.
Step-by-step explanation:
To find the weight of the marshmallow, we need to use the formula:
Weight = Density × Volume
Given that the volume of the marshmallow is 3.00 in³ and the density is 0.242 g/cm³, we can convert the volume to cubic centimeters and substitute the values into the formula:
Weight = 0.242 g/cm³ × (3.00 in³ × 16.39 cm³/in³)
After calculating the expression, the weight of the large marshmallow is approximately 11.8716 grams.
