The density of aluminum is 2.70g/cm3 and the density of chromium is 7.19g/cm3. If eual masses of aluminum and chromium are transferred to equal volumes of water in separate cylinders, which cylinder would have the greates volume change.
The easiest way to solve this problem is to assume some convenient mass, say 5 grams.
density = mass x volume and rearrange to
volume = mass/density.
volume Al = 5/2.70
volume Cr = 5/7.19
Draw conclusions from these data.
The density of aluminum is 2.70g/cm(cubid) and the density of chromium is 7.19 g/cm(cubid). If equal Masses (1g) of aluminum and chromium are transferred to equal columes of water in separate graduated cylinders, which graduated
water has a density of 1g/cm3 ; if 2 different pieces of the wood are put into water which will float and which will sink ? Wood 'a' has a density of 1.19g cm3 Wood "b" has a density of .67 g/cm3 Explain your answer?
In the figure, the radius of the submerged cylinder is 10 cm. The height is 25 cm. The cylinder is made of Aluminum whose density is 2.7g/cm3 the water density is 1g/cm3 What is the buoyant force on the cylinder? Repeat the
a)The element with the greatest density is osmium, which has a density of 22.6g/cm3. Calculate the mass of 32.1 cm3 of osmium. b)A team of students determined the density of a sample of wood to be 0.52 g/cm3. A handbook of
What volume of lead (of density 11.3 g/cm3) has the same mass as 304 cm3 of a piece of redwood (of density 0.38 g/cm3?(Answer in units of cm3. Okay, so this is like testing us over the basics, but I really can't get the answer! I
What is the density of a book whose mass is 1,800 g and whose volume is 300 cm3? *My Answer*You want to identify the numbers first, density = mass ÷ volume. Which would give you, 1800g ÷ 300 cm³ = 6 g/cm³. *Cant Figure Out
Use the 5-step method and be sure to include units where appropriate. Round your answers to the correct number of significant digits. Mass m Density = -------------- or D = ------ Volume v Adjust the density formula and solve the
