Analyze the graph below and answer the question that follows.
Yuki888 [10]

C. (-2,-2) is the answer.

<u>Explanation:</u>

When we reflect a point (x, y) across the y-axis, after the reflection, the y-coordinate tends to be the same, however the x-coordinate is changed into its opposite sign.

Here U(2,-2) is reflected across the y-axis then,

the y-coordinate -2 remains the same and the x-coordinate is transformed into its opposite that is the sign of the x-coordinate will be changed as -2.

So the new coordinates of U after reflection will be (-2,-2).

How many grams of aspartame (C14H18N2O5), also known as Nutrasweet, contain 1.98×1021molecules of aspartame?
Umnica [9.8K]

Answer:

0.97 grams

Explanation:

number of molecules=no of moles × Avogadros number

so

number of moles=nu.of molecules ÷ 6.02×10power23 = 1.98×10power21 ÷ 6.02×10p23=0.0033 mol

mass=nu.of moles× molar mass

molar mass of aspartame=

(14×12)+18+(2× 14.0067n)+(5×16)=294.0134 u

mass = 0.0033 ×294.0134 =0.97 gram
