• Part A A bakery measured the mass of a whole cake as 0.870 kg. A customer bought one slice of the cake and measured the mass of the slice as 0.1151 kg. What is the mass of the remaining cake, without the one slice? Express your answer in kilograms using the appropriate number of significant figures. • View Available Hint(s) ΑΣφ kg Part B An unknown object is placed on a balance, which then reads 6.118 g. Its volume is measured to be 3.04 cm³. Find the density of this object by dividing mass by volume. Express your answer in grams per cubic centimeter to the appropriate number of significant figures. • View Available Hint(s) Vα ΑΣφ ? g/cm3

Please answer question 11 parts A and B

Review T Constants i Periodic Table It will be helpful to remember two guidelines about significant figures. Part A 1. After multiplication or division, the answer cannot have more significant figures than any of the original A bakery measured the mass of a whole cake as 0.870 kg. A customer bought one slice of the cake and measured the mass of the slice as 0.1151 kg. What is the mass of the remaining cake, without the one slice? numbers. 2. After addition or subtraction, the answer cannot have more digits to the right of the decimal point than any of the original numbers. After determining the appropriate number of significant figures, round off your final answer. Express your answer in kilograms using the appropriate number of significant figures. View Available Hint(s) 1. If the first digit you drop is greater than or equal to 5, add 1 to the last digit you keep. You are rounding up. 2. If the first digit you drop is less than 5, do nothing to the digits you keep. You are rounding down. kg Part B An unknown object is placed on a balance, which then reads 6.118 g. Its volume is measured to be 3.04 cm³. Find the density of this object by dividing mass by volume. Express your answer in grams per cubic centimeter to the appropriate number of significant figures. • View Available Hint(s) Ηνα ΑΣφ ? g/cm³
