Convert everything to one base unit (let's do ft/s in this case)
There are 660 ft in a furlong and 2 weeks or 1209600 seconds in a fortnight
Multiply 537,600furlong and 660 ft/furlong and divide by 1209600 to get 293.333ft/s
The race car is already in ft/s
There are 30.48 cm in 1 foot and 3600 seconds in 1 hour. Multiply 9,000,000 by 1/30.48 and 1/3600 to get 82.02ft/s
THe peregrine falcon is the fastest
Answer:
12 g
Explanation:
We want to prepare 1 L of a 0.15 M NaOH solution. The moles of NaOH required are:
0.15 mol/L × 1 L = 0.15 mol
The molar mass of NaOH is 40.00 g/mol. The mass corresponding to 0.15 mol is:
0.15 mol × (40.00 g/mol) = 6.0 g
The starting solution is 50% by weight. The mass of solution that contains 6.0 g of NaOH is:
6.0 g NaOH × (100 g solution/50 g NaOH) = 12 g solution
The number of Protons.
(which is also the ATOMIC NUMBER)
1 mol = 6.023x10^23 number of molecules (Avogadro's number)
1 : 6.023x10^23
X : 4.91x10^22
(6.023x10^23)X = 4.91x10^22
X = 4.91x10^22/6.023x10^23
X = 0.082 Moles
2 are formed :) hope this helped!
