In a group assignment, students are required to fill 10 beakers with 0. 720 M CaCl2. If the molar mass of CaCl2 is 110. 98 g/mol and each beaker must have 250. ML of solution, what mass of CaCl2 would be used? Use Molarity equals StartFraction moles of solute over liters of solution EndFraction. 3. 13 g 38. 5 g 200 g 617 g.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
