It describes how, when particles/mc/elements react, despite forming different substances the mass is neither created nor destroyed but only converted.
MgqI% = the formula and mass for H20 and that should be your answer for water
Explanation:
n=given mass ÷molar mass
make given mass become the subject of the formula by
multiplying the molar mass on both sides of the equation.
n=0.473mol
given mass=??
molar mass=48
therefore,given mass=n×molar mass
=0.473×48
=22.704grams
mass in grams is 22.704grams
Metals are the most abundant
