Molar mass NaOH = 23 + 16 + 1 => 40.0 g/mol
number of moles:
10.0 g / 40 => 0.25 moles
Volume in liters:
500.0 mL / 1000 => 0.5 L
M = n / V
M = 0.25 / 0.5
M = 0.5 mol/L
hope this helps!
Answer:
Number of moles = 2.8 mol
Explanation:
Given data:
Number of moles of water = ?
Volume of water = 50 mL
Density of water = 1.00 g/cm³
Solution:
1 cm³ = 1 mL
Density = mass/ volume
1.00 g/mL = mass/ 50 mL
Mass = 1.00 g/mL× 50 mL
Mass = 50 g
Number of moles of water:
Number of moles = mass/molar mass
Number of moles = 50 g / 18 g/mol
Number of moles = 2.8 mol
The movement of sediments by wind, water, ice, or gravity is called erosion. Sediments are dropped in a new location. The process of dropping sediments in a new location is called deposition. Some of the small pieces are deposited on the ocean floor
Hope that helps :)
It's A; decomposition reactions involve one reactant becoming 2 or more products.
