Directions: The table shows the densities of four elements. Use the table to answer any questions that follow. (Photo 1) If this block has a mass of 173.7 grams, then what is this element? (Photo 2)

A

osmium

B

Calculate the molarity of the solution. 6.02 x 1022 molecules of hci (molecular weight = 36.5 g/mole) in 2.0 liters of water m

How many atoms are there in 5.70 mol of mg

Two metal blocks that have slightly different temperatures are placed next to one another. after five minutes, they both have lower but equal temperatures. according to the law of conservation of energy, what  most likelyhappened? energy was created inside the blocks.energy was destroyed inside the blocks.energy was absorbed into the blocks from outside the system.energy was transferred from the warmer block to the cooler block.
