Answer:
1st order
Explanation:
because magnesium has a coefficient of 1, it is first order
hydrochloric acid has a coefficient of 2, so it is second order
overall the reaction is third order (1+2)
Answer:
90g
Explanation:
We need to find the molar mass of C6H12O6. This is done below:
MM of C6H12O6 = (12x6) + (12x1) + (6x16) = 72 + 12 + 96 = 180g/mol
From the question, we obtained:
Volume = 1L
Molarity = 0.5M
Number of mole = Molarity x Volume
Number of mole = 0.5 x 1 = 0.5mol
Mass conc of C6H12O6 = number of mole x MM = 0.5 x 180 = 90g
