To find the number of moles we start by calculating the molar mass: M(C2H5OH) = 2*M(C) + 6*M(H) + M(O) M(C2H5OH) = 2* 12.01 + 6* 1.008 + 16 M(C2H5OH) = 46.068g
This is mass of one mole of ethanol. Total mass of ethanol can be calculated by using formula: m = N * M Where: m = total mass N = number of moles M = molar mass
We rearrange formula for N: N = m / M N = 508 / 46.068 N = 11.03
The value of x should be greater than or equal to -2. The number line from -2 to the entire right till ∞of the number line will satisfy this condition.
<h3>What is a number line?</h3>
A number line is just that – a straight, horizontal line with numbers placed at even increments along the length. It’s not a ruler, so the space between each number doesn’t matter, but the numbersincluded on the line determine how it’s meant to be used.
The value of x that will satisfy this condition can be found by simplifying the given inequality. Therefore, The giveninequality can be simplified as,
4x + 1 - 1 ≥ -8
4x ≥ -8
x ≥ -2
Hence, the value of x should be greater than or equal to -2. The number line from -2 to the entire right till ∞of the number line will satisfy this condition.
