To find the weight of the bag of sand, we need to multiply the number of grains by the weight of each grain.
Number of grains: 5,000,000
Weight of each grain: 6.7×10^−7 kg
Weight of the bag of sand = (5,000,000) * (6.7×10^−7) kg
Multiplying these values, we get:
Weight of the bag of sand ≈ 3.35 kg
So, the bag of sand that Maria brings home weighs approximately 3.35 kg.
Maria wanted to bring back 5 million grains of sand from her trip to the beach. Each grain of sand weighs approximately 6.7×10^−7 kg. How heavy is the bag of sand that Maria brings home?(1 point) Responses
