Using the given information, the  density  of metal B is  8.58 g/cm³     Calculating density   From the question, we are to determine the  density of metal B      From the given  information ,    55 g  of metal A is combined with metal B to create an  alloy  with mass  90 g   ∴ Mass of metal B in the alloy = 90 g - 55 g =  35 g     Now, we will determine the  volume of metal A  in the alloy   Using the  formula ,   Density = Mass / Volume   ∴ Volume = Mass / Density   Volume of metal A in the alloy = 55/12.7   Volume of metal A in the alloy =  4.33 cm³     Then, we will determine the  volume of the alloy    Volume of the alloy = 90/10.7  Volume of the alloy =  8.41 cm³     ∴ Volume of metal B in the alloy = 8.41 cm³- 4.33 cm³  Volume of metal B in the alloy =  4.08 cm³     Now, for the  density  of  metal B    Density = mass / volume   Density of metal B = 35 / 4.08   Density of metal B =  8.58 g/cm³     Hence, the  density  of metal B is  8.58 g/cm³ .
