Aspartame is a sweetner that is 160 times sweeter than sucrose (table sugar) when dissolved in water. The molecular formula of a
NikAS [45]

Answer:

  • <u><em>294.307 g/mol</em></u>

Explanation:

The first question for this statment is:

  • <em>Calculate the gram-formula-mass of aspartame. </em>

<em />

<h2>Solution</h2>

The chemical formula is:

        C_{14}H_{18}N_2O_5 .

The <em>gram-formula-mass </em>is calculated adding the masses for all the atoms in the molecular formula:

Atom       Number of atoms      Atomic mass       Total mass

                                                            g/mol            g/mol

C                     14                              12.011              14 × 12.011 = 164.154

H                     18                              1.008              18 × 1.008 = 18.144

N                      2                              14.007             2 × 14.007 = 28.014

O                      5                              15.999             5 × 15.999 = 79.995

                                                                                ===================

                                                            Total            294.307 g/mol

Answer: 294.307 g/mol

how does the increased salinity of the dead sea due to fertiliser industry impact the microscopic organisms that live there​
polet [3.4K]
The sea is called "dead" because its high salinity prevents macroscopic aquatic organisms, such as fish and aquatic plants, from living in it, though minuscule quantities of bacteria and microbial fungi are present. In times of flood, the salt content of the Dead Sea can drop from its usual 35% to 30% or lower.

How does incoming solar radiation make life on earth possible?
MrMuchimi

<span>Light from the sun provides energy for life’s processes. It enables the primary producers (photosynthetic organisms) such as phytoplankton and plants to produce organic molecules from abiotic factors. This energy is passed up as primary and secondary consumers consume these producers and this cycle continues up the foods chain/web. </span>
