The subject is: Converting between mass and amount (number of moles) and converting between mass and number of atoms and the mole concept. I already know the answers I just need someone to explain (very clearly cause i am not strong in chemistry) how to get the answers. Thanks so much!1.) Calculate the amount of copper (in moles) in a 35.8-g pure copper sheet. Answer: 0.563 mol Cu2.) Calculate the mass (in grams) of 0.473 mole of titanium. Answer: 22.6 g Ti3.) How many carbon atoms are there in a 1.3- carat diamond? Diamonds are a form of pure carbon. (1 carat 0.20 grams) Answer: 1.3 x 10 ^ 22 C atoms4.) Calculate the mass of 2.25 x 10 ^ 22 tungsten atoms. Answer: 6.87 g W5.) A titanium cube contains 2.86 x 10 ^ 23 atoms. What is the edge length of the cube? the density of titanium is 4.50 g/cm^3. Answer: L 1.72 cm6.) Find the number of atoms in a copper rod with a length of 9.85 cm and a radius of 1.05 cm. The density of copper is 8.96 g/cm ^3. Answer:2.90 x 10 ^24 Cu atoms
1.) Divide the given mass with molar mass of Cu. 2.) Multiply the given mole with molar mass of Ti. 3.) Convert 1.3 carat into grams (conversion is given) Divide the resulting mass with molar mass of C. Multiply the resulting number of moles with the Avogadro's number. 4.) Divide the # of atoms with Avogadro's number. Multiply the answer with molar mass of W. 5.) Divide the # of atoms with Avogadro's number. Multiply the answer with molar mass of Ti. Divide the answer with the density to get the volume. Using the formula of volume of cube, solve for L. 6.) Solve for the volume using this formula: V pi x r^2 x L Multiply the answer with the density of Cu to solve for mass. Divide the mass with molar mass of Cu to get moles of Cu Multiply the answer with Avogadro's number.
There's a code. Take it to a repair shop! AZ doesn't work on vehicles, they sell parts.
My sisters light came on in her durango too, come to find out sometimes the engine light will come on when its time for an oil change. take it to the dodge house if it needs an oil change there they will also reset your light and it will go off.
