One is rows the other is columns
Answer:
10-10 above the 0 is positive and the ones below is - (negitive)
Explanation:
volume of Ni = 25 nL = 25 x 10⁻⁹ L
mol Ni = 25 x 10⁻⁹ L x 1.25 mol/L = 3.125 x 10⁻⁸
mass = mol x Ar Ni
mass = 3.125 x 10⁻⁸ x 59 g/mol
mass = 1.84 x 10⁻⁶ g = 1.84 μg
Answer:
According to the law of conservation of mass, the mass of reactants will be equal to the mass of the products.
