Reptile [31]

1.54 x 10⁶kW

Explanation:

The problem here is converting from megawatts into kilowatts.

  Given 1540megawatts.

The mega- and kilo- watts are prefixes that denotes multiples of units.

  1 megawatt = 10⁶watts

  1 kilowatt = 10³watts

Now given 1540megawatts power to Kilowatt power;

   We see that :

   1000kW = 1mW

 1540mW x \frac{1000kW}{1mW} = 1.54 x 10⁶kW

You react 2.33 g of iron (III) chloride with 50.0 mL of 0.500 M solution of sodium phosphate to
nikklg [1K]

Answer:

2.33g of iron (iii) chloride

50.0 mL of 5.00 M of sodium phosphate

FeCl3 + Na3PO4 > Fe(PO4) + 3NaCl

mol = conc × vol = 0.5 × 50/1000 = 0.025 mol Na3PO4

from the equation:

1 mol of Na3PO4 reacts with 1 mol FeCl3 = 3 mol of NaCl

0.025 mol = x

x = 0.0025 × 3 = 0.075 mol NaCl

mass = 0.075 g × 59 g/mol = 4.425 g NaCl

i guessed all of this so i dont know i it is correct
