Alex lives in Arizona. He plants flowers in a pot with new soil mixed with fertilizers, and he places the pot on his back porch.

Since he’s watering it and it’s getting sun, i would say it’s because the soil isn’t rich enough and it doesn’t have the nutrients it needs for the plant to grow.

Which of the following is not the same as 12.5 millimeters? 0.0000125 km 0.00125 hm 0.0125 m 1.25 cm
erma4kov [3.2K]
1 mm (millimeter) = 0.000001 km (kilometer)
12.5 mm = <span>0.0000125 km

1 mm = </span><span>0.00001 hm (hectometer)
12.5 mm = </span><span>0.000125 hm

1 mm = </span>0.001 m (meter)
12.5 mm = 0.0125 m

1 mm = 0.1 cm (centimeter)
12.5 mm = 1.25 cm

So the only one of the answer choices that doesn't equal 12.5 mm is 0.00125 hm, since 12.5 mm is <span>0.000125 hm.

Answer:
</span><span>0.00125 hm

What is the concentration created when 380.0g of Pb(NO3)2 is added to 330.0 mL of solution?
Juliette [100K]

The concentration of lead nitrate is 3.48 M.

<u>Explanation:</u>

The molarity can be found by dividing moles of sucrose by its volume in litres. We can find the number of moles of sucrose by dividing the given mass by its molar mass. Now we can find the moles as,

Here mass of Pb(NO₃)₂ is 380 g

Molar mass of Pb(NO₃)₂ is 331.2 g/mol

Number of moles = $\frac{given mass}{molar mass}

                              =  $ \frac{380 g }{331.2 g/mol}

                              = 1.15 moles

Volume in Litres = 330 ml = 0.33 L

Molarity = $\frac{Moles}{Volume (L)}

          = 3.48 mol/L or 3.48 M

So the concentration of lead nitrate is 3.48 M.
