This is kind of going to sound complicated...but here you Go!
Lets start off with MM:
<span>The millimetre or millimeter is a unit of length in the metric system, equal to one thousandth of a metre, which is the SI base unit of length. Therefore there are thousand millimetres in a metre. There are ten millimetres in a centimetre. </span> 2nd, CM:
A centimetre (international spelling as used by the International Bureau of Weights and Measures; symbol cm<span>) or centimeter (American spelling) is a unit of length in the metric system, equal to one hundredth of a metre, centi being the SI prefix for a factor of 1100. </span> 3rd, M: <span> The basic unit of length in the metric system; it was originally planned so that the circumference of the Earth would be measured at about forty million </span>meters<span>. A </span>meter<span> is 39.37 inches. Today, the </span>meter<span> is defined to be the distance light travels in 1 / 299,792,458 seconds.
And Last, KM:
</span>The kilometre (International spelling as used by the International Bureau of Weights and Measures; SI symbol: km<span>; /ˈkɪləmiːtər/ or /kɪˈlɒmɪtər/) or kilometer (American spelling) is a unit of length in the metric system, equal to one thousand metres (kilo- being the SI prefix for1000). </span> So From all this information that i gave you, you might be thinking:
"Why on Earth Did you Give me ALL Of this when what i only needed is the ANSWER???"
Well, i gave you all of this so you could have an IDEA of what all these measurements and how HUGE they can be BEFORE i Give you The "Answer". So as Final or Result, they Biggest Measurements from ALL of the Above would be:
"KILOMETER"
1 km = 1000000 mm (Millimeters)
1 km = 100000 cm (Centimeters)
1 km = 1000 m (Meters)
Hope this ALL Helps! Took Me Time! Have A Wonderful Day! :)
Molarity is defined as the no. of moles of a solute per 1.0 L of the solution.
M = (no. of moles of solute)/(V of the solution (L)).
<em>∴ M = (mass/molar mass)of NaCl/(V of the solution (L)).</em>
<em></em>
<em>∴ mass of NaCl remained after evaporation of water = (M)(V of the solution (L))(molar mass)</em> = (0.45 M)(0.43 L)(58.44 g/mol) = <em>11.31 g.</em>
Explanation:because if u divide the the equation by 2 u well get the same answer you can multiply but that will take longer with the invisible zeros and stuff like that but the answer is 2c12 and on the real FSA u can pull out ur phone and cheat just make sure the teacher is not watching just playing with you DONT DO THAT YOU WILL GET IN SERIOUS TROBLE KIDS DO NOT DO THIS KN THE REAL DAY OF THE FSA PLEASE DONT DO IT YOU WILL GET IN SERIOUS TROUBLE WELL THATS IT FOR TODAY SO HAVE A GREAT DAY THIS IS TO PUT PRESSURE ON YOU
A physical property is an aspect of matter that can be observed or measured without changing it. A chemical property may only be observed by changing the chemical identity of a substance.
