Answer:
3 mole
Explanation:
2 moles of Ag give 1 mole of Mg(NO3)2
5 moles of Ag will give 5×1÷2 of Mg(NO3)2
=2•5 =3
Silicon dioxide is suitable for lining furnaces because of its very high melting point of 1,600 to 1,725 degrees celcius.
Measurements may be accurate, meaning that the measured value is the same as the true value; they may be precise, meaning that multiple measurements give nearly identical values (i.e., reproducible results); they may be both accurate and precise; or they may be neither accurate nor precise. The goal of scientists is to obtain measured values that are both accurate and precise.
Suppose, for example, that the mass of a sample of gold was measured on one balance and found to be 1.896 g. On a different balance, the same sample was found to have a mass of 1.125 g. Which was correct? Careful and repeated measurements, including measurements on a calibrated third balance, showed the sample to have a mass of 1.895 g. The masses obtained from the three balances are in the following table:
