A scientist makes a measurement and gets a value of 683. s. The true value is 600. s . Calculate the absolute and relative error of the scientist's measurement. Round your answers to a reasonable number of decimal places. Also be sure your answers include any necessary symbols.

According to the copper-nickel phase diagram, the composition at the 1300°C liquidustemperature is about 43 wt% Ni.In order to determine the amount of nickel that must be added to 1.75 kg

Ni, it is necessary to use Equation 4.3a.If we letmNirepresent the mass of nickel required, then Equation4.3a takes the form

43 wt% Ni=mNi1.75 kg+mNi×100

And solving this expression formNileads tomNi= 1.32 kg
