First, determine the weight of the object while wet. Using a scale, we find the object to be 20g while wet. Next, determine the weight while dry. After drying the object, we weigh it again and find that the weight is 10g. Finally, calculate the moisture content. Using the formula we find the moisture content to be 50%.
