2. An automobile antifreeze mixture is made by mixing equal volumes of ethylene glycol (SG= 1.114; MW = 62.07 g/mole) and water at 20°C. The density of the mixture is 1.070 g/mL. Express the concentration of ethylene glycol as a) Volume percent b) Mass percent c) Molarity

Question 2 You may need to use a special periodic table to answer the following question, the table is attached in the images below. Please show all of your work so I can understand going forward. Solve the following for m. Express your answer as an integer. a) 37 −150/? = −13

Rank the masses of the elements from lightest to heaviest. To rank items as equivalent, overlap them. B, Cr, Li, Pb, Ca, Cu, O, Al, I, Mg

The atomic mass of bromine is 79,904 amu. The atomic mass of the Br-81 isotope is 80.9163 amu and its relative abundance is 49.31%. What is the relative abundance and atomic mass of the Br-79 isotope?

A lead atom has a radius of 177 pm. To cover a distance of 2.17 mm, how many lead atoms would have to be put side by side?

An element has three naturally occurring isotopes with the following masses and natural abundances: Isotope 1 2 3 mass (amu) % abundance 24.9858 23.9898 25.9825 10.13 79.13 10.74 Identify the element, give the name of the element.

The element boron has two stable isotopes: boron-10 (10.0129 u) and boron-11 (11.0093 u). The periodic table reports a mass for boron as 10.811. What is the natural abundance of each boron isotope?

~ A robot spacecraft returned samples from the planetesimal 98765 ALEKS, located in the outer Solar System. Mass-spectroscopic analysis produced the follow data on the isotopes of tin in these samples: mass relative (amu) abundance 114 Sn 113.9 52.% 116 Sn 115.9 isotope esc Use these measurements to complete the entry for tin in the Periodic Table that would be used on 98765 ALEKS. Round your entry for the atomic mass to 3 significant digits. Caution: your correct answer will have the same format but not necessarily the same numbers as the entry for tin in the Periodic Table we use here on Earth. Explanation ! 0 Sn 0 1 Q A ?
