Anomalous data on a graph would show up as say a very high or very low value which does not fit in with the normal values which may be background values.If it was a straight line graph then the anomalous point would plot well above or below the line or if it was a bar graph ie a histogram it would be much higher or lower than the surrounding data. In mineral exploration, anomalies are looked for in say geophysics or geochemistry data values for high or low magnetism or conductivity or high chemical values indicating the presence of valuable minerals at that point.

How many kilograms of NH3 are needed to produce 1.90x10^5 of (NH4)2SO4? Answer in scientific notation

leva [86]

Molar mass :

NH₃ = 17.0 g/mol

(NH₄)₂SO₄ = 132 g/mol

2 NH₃ + H₂SO₄ = (NH₄)₂SO₄

2 x 17 g NH₃ ------------ 132 g (NH₄)₂SO₄
( mass NH₃) ------------ 1.90 x 10⁵ (NH₄)₂SO₄

( mass NH₃) = (1.90 x 10⁵) x 2 x 17 / 132

( mass NH₃) = 6460000 / 132

( mass NH₃) = 48939.39 g

in kg :

48939.39 / 1000 = 48.93 kg = 4.893 x 10¹ kg

What would be the mass of 3 moles of water molecules?

ankoles [38]

Answer:

$\boxed {\boxed {\sf A. \ 54 \ grams }}$

Explanation:

To convert from moles to grams, we must use the molar mass.

Recall that water's molecular formula is H₂O. It contains hydrogen and oxygen. Look up the two elements masses on the Periodic Table.

Hydrogen (H): 1.008 g/mol
Oxygen (O): 15.999 g/mol

Now, use these masses to find water's mass. The subscript of 2 tells us there are 2 atoms of hydrogen, so we multiply hydrogen's mass by 2 and add oxygen's.
