We need more information on this question.
The climatology method of forecasting uses averages to predict future weather.
Answer: B
Explanation
The satellites and advanced technologies have helped meteorologists to forecast accurately.
There are four types of forecasting methods prevailing now.
They are climatology method, persistence method, analog method and trends method.
The persistence and trends method uses the previous day forecast and compare with today's condition to forecast about future.
The analog method is a complex method where the forecasting is done by comparing present weather condition with a similar condition occurred in the past to predict for future.
The climatology is the simplest method which uses average of weather conditions observed in the previous days to get accurate forecast for future.
Answer is 334.35 g.
<em>Explanation:</em>
n = m/M
Where n is the number of moles of given substance (mol), m is the mass (g) and M is the molar mass of the substance (g/mol).
n = 3.99 mol
m = ?
M = 83.798 g/mol
By applying the formula,
3.99 mol = m / <span>83.798 g/mol
</span> m = 3.99 mol x <span>83.798 g/mol
</span> m = 334.35 g
D. metamorphic rock melts and crystallizes to become igneous rock <span />
To find moles in this sample, you would divide grams by molar mass of ethyl alcohol
(18.0g)/(46.07g/mol) = 0.391mol C2H6O
